printers on a Windows Server 2003 print server can greatly reduce the administrative load

associated with maintaining a print infrastructure.

Server Consolidation

Many companies are achieving significant savings by consolidating their core services on

Windows Server 2003. Consider consolidating core services, such as user logon, DHCP, DNS,

and so on if you want to take advantage of the features and performance of Windows Server 2003

while preserving your existing Windows NT 4.0 domain structure. For example, you may want to

do this if you need to support earlier systems that cannot be upgraded or if you want to upgrade

systems incrementally.

The benefits of a core service consolidation include increased performance, higher availability,

reliability, and access to new features and technologies. Windows Server 2003 can provide faster

and more efficient logon and networking and name resolution for a Windows NT 4.0 domain.

Consolidating services also provides an opportunity for hardware consolidation as redundant

servers are eliminated. In addition, a consolidated environment is easier to manage, not only

because it is more centralized, but also because Windows Server 2003 offers improved

management features.

DNS and DHCP

A Windows Server 2003 domain member server in a Windows NT 4.0 domain can be used to

host DNS for the domain. In this way, you can take advantage of the higher reliability and

performance of Windows Server 2003 DNS, as well as its security-enhancing features, such as

dynamic update and support for Internet Engineering Task Force (IETF) RFC2535 DNS security

extensions.

DHCP improves user mobility by making it easier for users to connect to the network wherever

they are. It also simplifies IP address management administrators. Windows Server 2003 includes

enhanced management tools for DHCP, including automated backup and restore and upgrade of

the DHCP database. These tools eliminate many time-consuming tasks that formerly had to be

done by hand.

Generally speaking, when using Windows Server 2003 for DNS and DHCP, the main

consideration for determining how many servers you require is not server performance, but rather

geographical locations and network performance across locations. In many organizations, this

reality can mean eliminating the bulk of their existing servers, resulting in hardware savings.

Incremental Upgrade

Core services consolidation has the advantage of being an important incremental step on the way

to an upgrade to Windows Server 2003 domains and forests running with Active Directory.

Ultimately, many organizations will want to take advantage of the opportunities provided by

implementing Active Directory. However, the idea of upgrading to Active Directory can be a

challenging proposition. In the mean time, upgrading core services tends to be less complex and

enables administrators to start getting comfortable with the new operating system.
